Liftable HUD device

Abstract

The invention discloses a liftable HUD device, and belongs to the technical field of head-up display. The liftable HUD device comprises a mounting box, a mounting plate and a placement table; the mounting plate is arranged in the mounting box, the placement table is rotatably connected to the mounting plate, a first mounting table and a first motor are fixedly connected to the inner wall of the bottom of the mounting box in sequence from left to right, and a first threaded rod is fixedly connected to the output end of the first motor; the end, away from the first motor, of the first threaded rod is rotationally connected to the inner wall of the side wall of the mounting box, and the first threaded rod is in threaded connection with a second mounting table. According to the device, the HUDdisplayer can be fixed more stably through cooperation of a third threaded rod and a clamping plate, the height and the angle are automatically adjusted through a first motor, a user can adjust the angle more conveniently, secondary adjustment can be conducted on the angle through a second motor, and the device is suitable for drivers with different driving habits.

Description

technical field [0001] The present invention relates to the technical field of head-up display technology, in particular to a liftable HUD device. Background technique [0002] Head-up display (HUD) for short, can project important information on the windshield, and the driver can obtain information from the windshield without bowing his head. However, there is a large difference in the height of the driver. The existing head-up display is suitable for driving Because of the difference in the height of the driver, a support frame is often installed to adjust the projection height of the head-up display. In order to facilitate the rotation and adjustment of the angle of the head-up display, the support frame is generally set higher, so it is easy to block the driver's line of sight and cause a safety hazard. [0003] In the prior art, Chinese patent authorization number: CN210069328U patent, publication date: 2020-02-04, a HUD device that can be raised and lowered, including ...

[0002] Head-up display (HUD) for short, can project important information on the windshield, and the driver can obtain information from the windshield without bowing his head. However, there is a large difference in the height of the driver. The existing head-up display is suitable for driving Due to the difference in the height of the driver, a support frame is often installed to adjust the projection height of the head-up display. In order to facilitate the rotation and adjustment of the angle of the head-up display, the support frame is generally set higher, so it is easy to block the driver's line of sight and cause a safety hazard.

[0003] In the prior art, Chinese patent authorization number: CN210069328U patent, publication date: 2020-02-04, a HUD device that can be raised and lowered, including a base, a housing, a motor, a fixed frame and a retractable support frame, the base There is a groove for accommodating the housing, the housing is rotatably connected with the fixed frame, the fixed frame is connected with the bottom of the groove through the support frame, and the output shaft of the motor is connected with Screw rod, the screw rod is used to control the lifting of the support frame, the base is provided with a switch button and a controller, the switch button is electrically connected to the controller, and the controller is electrically connected to the motor connection, the interior of the housing is provided with several clamping blocks, and several of the clamping blocks are respectively connected to the interior of the housing through the first spring. The occupied space affects the use; 2. When the shell adjusts the angle, the display is clamped by the spring, which has a single function and cannot clamp various types of displays.
